GLASS-DRAWING MACHINE.

Specification of Letters Patent.

Patented Sept. 28, 1920.

Application filed April 12, 1919. Serial No. 289,634.

To all whom it may concern:

Be it known that I, FELIX L. GOFFAUX, a citizen of the United States,residing at Arnold, in the county of Westmorelandand State ofPennsylvania, have invented new and useful Improvements in Glass-DrawingMachines, of which the following is a specification.

This invention relates to improvements in glass drawing machines and theprincipal object of the invention is to provide means for drawingseveral sheets of glass at one time.

Another object of the invention is to provide means for drawing arectangular tube of glass and to provide roller means for engaging theinner corners of said tube with means for inserting or Withdrawing theroller means through the bait.

Another object of the invention is to so construct the bait that enoughof the melted glass will be held thereby so as to prevent too rapidcooling off of said bait.

The invention also consists in certain other features of constructionand in the combination and arrangement of the several parts, to behereinafter fully described, illustrated in the accompanying drawingsand specifically pointed out in the appended claims.

In describing my invention in detail, reference will be had to theaccompanying drawings wherein like characters denote like orcorresponding parts throughout the sev eral views, and in which Figure 1is a side view showing a portion of the elevator shaft with the elevatorand the bait attached thereto;

Fig. 2 is a longitudinal section through the apparatus and showing theroller means in place;

Fig. 3 is a cross section;

Fig. 4 is a detailed view of the roller means with the rollers in closedposition;

Fig. 5 is a cross section through the bait;

Fig. 6 is a detail view showing how the roller engages with the cornerof the glass tube.

In these views 1 represents the elevator shaft and 2 the elevator. Thiselevator is raised and lowered by means of the cables 3 passing oversuitable pulleys which are operated as usual. The elevator is providedwith the projecting hooks 4 for en aging the holes 5 in the uprights 6on the bait 7. This bait comprises a rectangular frame 8 made of channeliron with the channel outermost. The uprights 6 are secured to the innerfaces of two of the opposing sides of said frame and each pair of theupper parts of said uprights are connected together by the cross piece 9which is provided with the holes 10 for receiving the removing hooks.Each side of the frame has hinged to its outer face a channel bar 11with the channel facing inwardly so that the channel frame and saidchannel bars form a chamber 12. The lower edges of the inner and outerbars are cut away to provide a slot 13 in the bottom of the frame whichcommunicates with said chamber. Thus when the bait is dropped in themolten material, the chamber will be filled thereby and thus the baitwill be prevented from cool ing off too rapidly. As the elevator israised to withdraw the bait from the receptacle containing the moltenmaterial a rectangular tube of glass will be formed. After the bait hasbeen drawn up a certain distance I pass a tubular member 14 through theshaft and the bait with its lower end projecting into said tube. Theupper end of said tubular member is adjustably supported at the top ofthe shaft. A rod 15 passes through said member and four arms 16 arepivotally connected with the lower end of said rod. The outer ends ofthese arms are forked as at 17 and rollers 18 are journaled in .saidforks. As shown, the periphery of each of said rollers is ofsubstantially wedgeshape in cross section so that when said roller isplaced in the corner of the tube it will engage with the edges of thetwo adjoining sheets. The arms are pivotally connected with the lowerend of a tubular member by the links 19 so that by moving said rod 15vertically the rollers will be moved into or out of engagement with thecorners of the tube. By this means the rollers may be easily passedthrough the device or removed therefrom. It will be seen that therollers may contact with the glass tube at any desired point by means ofthe adjustability of the tubular member 14. After a drawing is completedthe holes 10 are engaged by hooks carried over suitable pulleys and thenthe elevator is detached from the bait and pulled up to the top of theshaft with the rollers in folded position. The bait is then lifted andcarried to the proper place for capping off.

When it desired to clean the bait it can be easily done by swinging theouter bars 11 away from the inner frame to open the frame, said framesforming a chamber and chamber.

It is thought from the foregoing description that the advantages andnovel features of my invention Will be readily apparent.

I desire it to be understood that I may make changes in the constructionand in the combination and arrangement of the several parts, providedthat such changes fall within the scope of the appended claims. 7

What I claim is I 1. A device of the class described comprising anelevator, a bait of rectangular form carriedby saidelevator, avertically movable supporting member and rollers carried by'said memberfor engaging the glass tube being formed.

2. A device of the class described comrisin an elevator a rectan ularbait formed of a frame of channel iron, an outer frame of channel 1I'0I1hlnged to the lnner supporting means carried by the inner frame.

3. A device of the class described comprising a shaft, an elevatortherein, a rectangular bait carried by said elevator, a tubular memberadjustably connected with the shaft and extending through said elevatorand bait, a rodpassing through said tubular member and verticallymovable therein, arms pivotally connected to the lower end of said rod,links connecting said arms to the lower end of the tubular member androllers carried by the outer ends of said arms.

in testimony whereof I afliX my signature.

BELLA L. GOFFAUX.
